problems. It is useful for installers and meter shop personnel. Foremost, it provides
diagnostic information through the TNS and TWACS NG systems which give you
a better assessment of problem conditions before field personnel are dispatched.
There are three essential sources of diagnostic information:
• The Intelligent End Device (IED) status, including leak detection, tamper
detection, and port assignment.
• Among the four bytes of total consumption readings are specific bits of data
for port-specific status information.
• The EMTR-3 diagnostic indicators.
Performing Remote Analysis (TNS)
Complete the following steps to determine if a field visit is required for an
unresponsive meter. You can end the procedure at any step and correct the problem
when a cause of failure is determined.
1.
Check the AMRCOMMFAIL table for TWACS serial numbers that have
excessive AMR Communication Failure counts. This enables you to
identify meters that are consistently failing AMR.
If the meter fail count in the AMRCOMMFAIL table is equal to or greater
If the meter fail count in the AMRCOMMFAIL table is equal to or greater
than the MaxFailCnt in the TNSDEFAULTS table, the Quality Code (QC)
will be set to RO (Retry Override). When the quality code is RO, the meter
unit map will have changed in the AMRCMDLST2WAY table. The meter
will be attempted the first time, but will not be issued subsequent retries and
must be read manually.
2.
Determine if any error messages have occurred during AMR by checking
the SCE Notification log for any associated hardware issues for the meters
that are not communicating.

The Notification log contains important information about the status of
equipment and is automatically updated by TNS and the SCE. For detailed
information about the Notification log and error messages, see the
Notification Log section of the SCE Logs chapter in the TNS Operational
Process Guide (Y10352TM) and the Notification Log section in the SCE
Maintenance chapter of the TNS End User Guide (Y10285TM).
